2015-03-24libm: honor NO_LONG_DOUBLE in ldouble_wrappersBernhard Reutner-Fischer
Fixes SH build breakage due to attempts to define hidden defs for unavailable long double functions. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2014-11-10Config.in.arch: enable long double math for xtensaMax Filippov

2013-02-20Config.in: Introduce symbol for arches with deprecated syscallsMarkos Chandras
Linuxthreads(old and new) need deprecated syscalls to build. Existing architectures support these system calls but new architectures don't. This symbol has no functional change apart from hidding the Linuxthreads symbols from arches that don't support them.

2013-01-26buildsys: allow the toolchain to search its dirs for kernel headersMike Frysinger
Setting KERNEL_HEADERS up to the exact path all the time is a pita, especially when the toolchain is often times already configured to do the right thing. So if the user has set that to "", don't force any specific paths. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-01-10buildsys: remove superfluous default nBernhard Reutner-Fischer
kconfig's default defaults to n so spelling out default n is redundant Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-06-15Config.in.arch: remove UCLIBC_FORMAT_ELF config optionPeter S. Mazinger
Unused option (and is in !ARCH_HAS_MMU guarded section, but depends on ARCH_HAS_MMU) Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2011-07-01Config.in.arch: Free UCLIBC_HAS_FPU setting from depending on UCLIBC_HAS_FLOATSKhem Raj
UCLIBC_HAS_FLOATS and UCLIBC_HAS_FPU are denoting two different aspects. UCLIBC_HAS_FLOATS covers the floating point operations which has nothing to do if you have FPU or not. Signed-off-by: Khem Raj <raj.khem@gmail.com>

2009-09-14Revert "default ?conf to native arch"Bernhard Reutner-Fischer
This reverts commit 6625518cd6894338937a74ca6b9187b7b8167b03. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2009-08-25default ?conf to native archBernhard Reutner-Fischer
Default is now the native arch, you can start a fresh .config via 'make ARCH=ia64 menuconfig'. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2009-07-26enable sbrk() for everyoneMike Frysinger
The sbrk() function can be used to merely query sizes and for that, no-mmu works the same as mmu. It can also sometimes increase data segments on no-mmu systems provided the trailing memory is free. So, there is no real reason to exclude this function for no-mmu ports. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2004-01-16Fixup selection of endianness, since select does not work on choiceEric Andersen
items, we have to declare what endianness cpus are capable of supporting and work using dependancies.

are implemented in hardware or via kernel emulation doesn't matter to the libc code.
2003-11-05Do not provide a default for endianness. This needs to be selectedEric Andersen
on a per-arch basis, or left to the user to choose.
2003-11-04Rework the config system. Better utilize the Kconfig languageEric Andersen
which should simplify enabling arbitrary architectures. -Erik
